“Peter and I are delighted to announce our pregnancy,” Drew tells PEOPLE. “We can’t wait to introduce Micah to his little brother or sister.”

On the season finale of Grey’s, it was revealed that Drew’s character, April Kepner, is expecting her first child with her onscreen husband Jackson Avery, played by new dadJesse Williams.
And while she’ll be busy balancing her expanding family with the upcoming season of her hit show, Drew recently admitted her son makes motherhood look easy.

“He does have tantrums now and again, but for the most part, he’s incredibly sweet and funny and such a good boy,” she said. “He’s a lot easier than a lot of toddlers. I’m very, very lucky.”
